Abstract

The invention relates to a vehicle headlight, comprising a housing (1) and modulatable light or IR radiation sources (4) which are arranged within the housing (1) and on a movable module support (5), and comprising an interface (2) for connection to an external vehicle processor (3), wherein an image sensor (6) for determining depth information from the backscatter radiation of the light or IR radiation sources (4) is arranged within the housing (1), and a processor (8) connected to the image sensor (6), which processor is connected via a modulator (9) to at least some of the modulatable light or IR radiation sources (4) arranged within the housing (1). It is proposed in accordance with the invention that the processor (8) is connected via a bidirectional data link (10) to the interface (2), and the image sensor (6) is arranged on the module support (5) or on an image sensor support triggered jointly with the module support (5). An application of ToF technology in automotive engineering which is fit for day-to-day use and suitable for series production is achieved in this manner by the best possible integration in conventional automotive engineering.

Claims

1. A vehicle headlight, comprising:

a housing (1) and modulatable light or IR radiation sources (4) which are arranged within the housing (1) and on a movable module support (5), and comprising an interface (2) for connection to an external vehicle processor (3), wherein an image sensor (6) for determining depth information from the backscatter radiation of the light or IR radiation sources (4) is arranged within the housing (1), and a. processor (8) connected to the image sensor (6), which processor is connected via a modulator (9) to at least some of the modulatable light or IR radiation sources (4) arranged within the housing (1), wherein the processor (8) is connected via a bidirectional data link (10) to the interface (2), and the image sensor (6) is arranged on the module support (5) or on an image sensor support triggered jointly with the module support (5).

2. A vehicle headlight according to claim 1, characterized in that the processor (8) is connected to the module support (5) and the image sensor support.
